SECOND LAW OF THERMODYNAMICS WITH QC-MUTUAL INFORMATION

摘要

I'd like to discuss generalizations of the second law of thermodynamics in the presence of quantum information processing such as quantum measurement and quantum feedback control.~(1,2) A quantum information content, referred to as QC-mutual information, is shown to play a crucial role. We also discuss the generalization of a quantum generalization of the Hatano-Sasa inequality for transitions between nonequilibrium steady states with quantum feedback control.
